A KNIFE-WIELDING robber is being hunted by detectives following a robbery at a convenience store.

The man brandished the blade in front of a manager at the the Lifestyle Convenience Store, Pen-y-Wain Road, Cardiff, and demanded money.

Detectives investigating the robbery at 9am on Tuesday, June 9, said he went behind the counter and left with cash from the till. He headed in the direction of Monthermer Road.

Officers released CCTV images of the suspect and are appealing for help in identifying the person responsible.

Detective Inspector Paul Andrews, head of CID in Roath and Cathays, said: "We will not tolerate robberies. Investigating them is a priority which has led to a nine per cent decrease in robberies so far this year.

"My advice to the person responsible is to hand himself in or expect a knock of the door from South Wales Police.

"We have recently arrested and charged a 17-year-old with six robberies which occurred at Roath Recreation Ground at the weekend and we are equally determined to catch the man responsible for carrying out this robbery in the Lifestyle shop.

"This was a cowardly attack on a shop owner who was working alone and was naturally extremely shaken up by what has happened.

"I would urge anyone who recognises the man in the CCTV or anyone else with information to contact us immediately."

The suspect is described as white, in his early 20s, around 5ft 11in tall, skinny, with small narrow eyes and a British accent. He was wearing a white hooded top which had a large distinctive black pattern on the front.
